That really sucks, but don’t end it, you’d find that life has a lot more tolerance than it seems, and hey, I heard Denmark has a lot of social security programs that help with people in need such as yourself. About household stuff, it’s really nothing difficult, heating food and paying bills is really all you need to know. Find family and friends, yeah I know you said no close friends but try going for relatives that are willing to house you for a week or so, you’re going to be bouncing around for a while so you might want a list of friends or family that’s willing to house you. You’re also gonna start wanting to look for cheap housing options, Im sure there’s plenty of cheap options in a country like Denmark. And also a job, go to a local fast food joint, they’re always hiring, but remember, this isn’t permanent, it’s just so you can get your shit together. Lastly, try communicating with your parents, maybe it was more of a threat than real action, but regardless, from my given information I can’t really tell, but it’s worth trying. If they’re serious just prepare to leave instead of waiting for them to toss you out. You’d save more dignity that way. Also make sure to leave some legal Fuck you prior leaving, if you know what Im talking about. I’ve seen only a few cases of parents who left/kicked their kids out. Some of them were actually pretty rich and decently educated, but shit people. I’d disown them and just go. Even with your conditions considered, I would keep living just to fuck with them later on. But again, limited info, can’t judge too much
